The terrifying video footage shows the three robbers wielding silver handguns as they rifle through the pockets of the owner of Willmohr Liquor and Wine and two employees, whom they forced to lie on the floor and tied up with duct tape.

Store owner Geoffrey George, 39, told The Post that the thugs – black men in their 20s wearing dark hooded jackets — spent two hours in his store at 1162 Willhmohr St., taking orders on the phone for cases of Ciroq, Petron and Hennessey.

Three other men worked outside, helping load the boxes into cars while George and his staffers lay on the floor, bound with the tape.

“They were calling their friends on the phone,” George said, recounting the Jan. 20 robbery. “They were saying, ‘What you want? What you want?’ ”

“There were three of them working inside, and three outside. They would set up a set of boxes by the door, and then when a vehicle pulled up, they [would] go out and put it in the car and then come back and set up the next order. They pulled the [window] shutters down so people didn’t know. They were taking the liquor in cases out to the cars.”

“They took all the top-shelf inventory,” said George, estimating that the robbers ultimately made off with “between $45,000 and $50,000,” nearly 100 cases, in high-end booze.

George said his shop, which opened in March 2013, was closed -– he and two staffers were working to reinforce wooden shelving — when the three men entered around midnight.

“We had the doors open because we were sawing the wood outside,” he said. “Three guys came up and one asked if we were still selling liquor. I told him, ‘No, we are fixing shelves, we are not open.’ ”

“Then the two other guys came up and pulled out their guns.

“They asked us to get on the floor inside and they duct-taped us, and they pulled down the shutters,” George said.
